I am at a crossroads; I injured my si joints with long-distance, heavy backpacking. I wound up in excruciating pain, that I used lidocaine applications, and naproxen, to diminish. Now I use a tens unit ( now 120 minutes every morning), sleep on 4” of gel mattress, and find walking and running help to prevent stiffness and inflammation. I did injections, and found great relief for 3 months,but wonder to try that again.( besides “the pain” of insurance when asked to pay “out of network” anesthesiologist. What are your go-to treatments that are cumulatively working.
